Score Ratings

Our ratings are live updated scores from our primary research database. They are based on primary and secondary research across 23 categories - 17 negative categories and 6 positive ones (Company Ethos and Product Sustainability). Find out more about our ethical ratings


Score table

The score table shows simple numerical ratings out of 20 for each product. The higher the score, the more ethical the company.

Move the sliders to customise these scores. 

Click on a product name to see the stories behind the score (subscribers only). 


Full Scorecard

The Full Scorecard shows the 'black marks' for each product, by each of the 17 negative categories. The bigger the mark, the worse the score. So for example a big black circle under 'Worker Rights' shows that the company making this product has been severely criticised for worker abuses.

Scores start at 14.  A small circle means that half a mark is deducted, a large circle means that a full mark is deducted.

Marks are added in the positive categories of Company Ethos and the five Product Sustainability columns (O,F,E,S,A).  A small circle  means that half a mark is added, a large circle means that a full mark is added.

The Full Scorecard is only available to subscribers. Click on the More Detail link at the top of the score table to access it.

Car Insurance


Car insurance is a legal requirement in the UK, so it’s not surprising that the insurance industry is huge, and not just in terms of sales each year. Insurers often hold vast investments in other companies, as we have explained in our home insurance guide.

In the UK alone, insurance companies manage investments equivalent to around 25% of the country’s net worth.

This means that they are indirectly financing everything from tar sands to the sales of arms. In this guide, we have tried to find the car insurance companies with the most ethical approach to investment.

Types of insurance

There are two types of insurance company: brokers and underwriters.

Brokers sell policies on behalf of one or more underwriters, and include well known brands such as Sainsbury and the AA. They make money by receiving a commission from the underwriter, once a policy is sold.

Underwriters are the companies that take most of the money from an insurance premium, but which also pay out when something goes wrong. They may not be as visible as the broker’s insurance brand. But it is an underwriter that will hold investments. They therefore wield a significant amount of power in the global economy. That is why we have focused on them for this report.

Just to make things more confusing, some underwriters do sell directly to the public, or belong to the same company group as the broker itself. Others may re-insure a specific risk via a different underwriter (basically insurance for the insurer).


What to look for?

In the UK alone, there are hundreds of brokers – too many to include in our reports, so our ranking tables only include underwriting companies.

Unfortunately, most of us will buy our policy through a broker, so you may have to do some extra digging. You can find the underwriter by looking at the ‘Key Facts’ document that the broker must provide when you are deciding to take out a policy. Comparison websites like Money Saving Expert sometimes also either provide these documents or tell you who the underwriter is.

How we rate companies

Several campaign groups have published reports about specific investments held by insurance companies (or the banks by which they are owned). We have marked down the companies named in these, and have included some more detail about the reports throughout the finance guides. Insurance companies appeared in Don’t bank on the Bomb, Unfriend Coal (see our home insurance guide); and Israel Report (see our current accounts guide).

We also looked for investments in specific companies, beginning with some of the largest in the UK and US such as WalMart, General Electric and Coca-Cola. Where the insurance company holds shares in, for example, a company criticised for pollution, it will also receive half a mark in the Pollution and Toxics column on the table.

Most companies lost multiple marks in this way. Where no ethical investment policy or shareholdings could be found for a company, it was assumed to have investments in companies criticised in all Ethical Consumer categories – as, sadly, is the norm in this industry. We also wrote to these companies to check there wasn’t a policy somewhere we hadn’t found.

Companies with an ethical policy on investments

A growing number of companies have some form of ethical policy on investments. But often these only exclude the most extreme players in a sector, for example those making cluster munitions or over 50% of profits from coal mining. We were looking for something a bit more robust, which crosses lots of sectors. Only one company in our car insurance guide had this: The Co-operative. We have outlined their ethical investment policy in the home insurance guide.


Table Highlights

Exemptions for those reporting well

Transparency around investments is rare in this sector. Very few companies publish shareholdings, let alone information about how they use them to steer those companies that they invest in. There were only two notable exceptions in our insurance tables: Aviva and AXA. They scored ‘Top of the Pile’ for transparency, and were not therefore marked down for their investments.



ClimateWise Membership

ClimateWise is a voluntary insurance industry initiative, focused on responding to the risks and opportunities of climate change. The companies involved commit to take action in many ways: through leading risk analysis, informing public policy, supporting climate awareness, and incorporating climate change into investment strategy. Almost all the companies in our table were signed up.

Ethical Consumer considers membership to be an important step for insurers towards addressing climate change: those who were not signed up therefore lost half a mark in the Climate Change category. Those companies were: Esure Group, Markerstudy Group, Ageas, J.C. Flowers & Co., Admiral, Legal & General, NFU Mutual, Liverpool Victoria, Covea, The Co-operative Group, American International, AXA, Marsh & McLennan, and Red Sands.


Tax avoidance

Tax avoidance is known to be pervasive in the financial sector, and the insurance industry appears to be no exception. Almost all those companies that had business abroad also appeared to have lots of high-risk subsidiaries registered in tax havens. Companies that got a worst rating for likely use of tax avoidance strategies lost a whole mark under Anti-Social Finance, and those that got a middle lost half a mark. The Co-op Group stands out as a FairTaxMark accredited company

Best: American International, Ageas, Admiral, Direct Line, Esure, Liverpool Victoria, The Co-op 

Middle: Covea, Lloyd’s of London

Worst: Allianz, Aviva, AXA, Markerstudy, Hiscox, J. C. Flowers & Co., Legal & General, Marsh & McLennan, Munich Re, NFU Mutual, Red Sands, RSA, Tesco

Red Sands even gave a history of Gibraltar’s (lax) tax laws on its website!


Don’t Buy

Insurance underwritten by Munich RE. The company not only received one of the lowest Ethiscores in our table, it was named in the IBFAN Don’t Bank on the Bomb report for funding nuclear weapons companies, and in the Unfriend Coal scorecard as a company that had only taken ‘baby steps’ towards divesting from and refusing insurance to coal companies.



Eco Car Insurance

Since the Green Insurance Company stopped trading, Co-operative Insurance was the only underwriter or broker we found that was offering a green car insurance policy.


Table: Cooperative Green Insurance


At Ethical Consumer, we are not completely convinced by the carbon offset approach, our feature discusses the issues with it. We were impressed, however, by the Co-operative Group’s policy on screening all investments, which the company sent to us. 


An ‘ethnic penalty’ for insurance?

The insurance industry appears to be racially profiling customers when giving quotes, a study in 2016 found. Those living in a majority ethnic-minority area were paying up to £450 more for their car insurance premiums, the report stated.

The research was based on data from the AA on all 124 postcode areas in the UK. It found that 60% of the price variation – which was present across both high and low income areas – could be accounted for by the difference in the ethnic composition of the area, up to 90% in some cases. The way insurers calculated their premiums “has definitely produced an inequality of outcome to the detriment of BME [black and minority ethnic] groups”.




Company Profile

J. C. Flowers is a private equity company which specialises in the financial sector. Amongst its investments are commercial banks operating in Russia, The Netherlands and Germany. These banks do not appear to have ethical policies governing their lending and therefore the group attracts marks for investments in areas including fossil fuels and factory farming.
